For ease of more fully understanding the technical solution according to the disclosure, following is a brief introduction of general used in some disclosure It reads.

Base station such as evolved node B (eNB) has the mutiple antennas for supporting MIMO technology.MIMO technology use so that Base station can support spatial reuse, wave beam forming and transmitting diversity using spatial domain.Spatial reuse can be used in identical frequency Above while transmitting different data flows.These data flows can be transmitted to single UE (can be classified as SU-MIMO skills to improve data transfer rate Art) or multiple UE are sent to increase overall system capacity (MU-MIMO technologies can be classified as).This is carried out by each data flow Spatial pre-coding (that is, using proportional zoom and phase adjustment of amplitude) and then by multiple transmitting antennas in downlink (DL) each stream through spatial pre-coding is transmitted on to reach.Data flow through spatial pre-coding is with different spaces signature ground The places (all) UE are arrived at, this enables in (all) UE, and each UE restores one or more data flows using the UE as destination. In uplink (UL), each UE transmits the data flow through spatial pre-coding, and it is each pre- through space that this so that base station can be identified for that The source of the data flow of coding.

Spatial reuse is generally used when channel conditions are good.When channel conditions are less advantageous, wave beam can be used to assign Shape concentrates emitted energy in one or more directions.This can be by carrying out spatial pre-coding with for use by more to data A antenna transmission is reached.In order to reach good covering in cell edge, single beamforming transmission that flows is in combination with transmitting Diversity uses.

In the following detailed description, the mimo system with reference to the support orthogonal frequency division multiplexing (OFDM) on DL is described to connect The various aspects of networking.OFDM is the spread spectrum modulated data on several subcarriers in OFDM symbol (Symbol). These subcarriers are separated with precise frequency.The separation provide allow a receiver to from these subcarriers restore data " just The property handed over ".In the time domain, guard interval (for example, cyclic prefix) can be added to each OFDM symbol to do between OFDM symbol to fight It disturbs.UL can use the single-carrier frequency division multiple access (SC-FDMA) of the ofdm signal form extended through discrete Fourier transform (DFT) To compensate height power ratio (PAPR).

Next the radio protocol architecture that user plane and control plane are used in LTE (long term evolution) is explained.For UE and The radio protocol architecture of eNB is shown to have three layers：Layer 1, layer 2 and layer 3.1 (L1 layers) of layer are lowermost layers and realize various objects Manage layer signal processing function.L1 layers will be referred to herein as physical layer.Layer 2 (L2 layer) on physical layer and be responsible for UE and Link between eNB on physical layer.

In user plane, L2 layers include media access control (MAC) sublayer, radio link control (RLC) sublayer and Packet Data Convergence Protocol (PDCP) sublayer, they are terminated on network side at eNB.UE can also have several on L2 layers A upper layer is included in network layer (for example, IP layers) and the other end for terminating in connection that network side terminates at PDN Gateway The application layer of (for example, distal end UE, server etc.).

PDCP sublayers provide the multiplexing between different radio carrying and logic channel.PDCP sublayers are also provided to the upper number of plies According to the header-compressed of grouping to reduce wireless radio transmission expense, safety, Yi Jiti are provided by encrypting packet For supporting switchings of the UE between each eNB.Rlc sublayer is provided to the segmentation and refitting of upper layer data packet, to losing data The re-transmission of grouping and reordering for packet is disordered because of caused by hybrid automatic repeat-request (HARQ) and connect to compensate It receives.Media access control sublayer provides the multiplexing between logic channel and transmission channel.Media access control sublayer is also responsible for distributing a honeycomb between each UE Various radio resources (for example, resource block) in cell.Media access control sublayer is also responsible for HARQ operation.

In the control plane, be used for UE and eNB radio protocol architecture for physical layer and L2 layers essentially identical, area It is not do not have header suppression function for control plane.Control plane further includes the radio resource control in layer 3 (L3 layers) (RRC) sublayer.RRC sublayers are responsible for obtaining radio resource (that is, radio bearer) and are responsible for using between eNB and UE RRC signaling configures each lower layer.

Briefly introduce the various signal processing functions that base station side realizes L1 layers (that is, physical layer).These signal processing functions Including encode and interweave forward error correction (FEC) to facilitate UE and based on various modulation schemes (for example, binary phase shift keying (BPSK), quadrature phase shift keying (QPSK), M phase-shift keying (PSK)s (M-PSK), M quadrature amplitude modulations (M-QAM)) to signal constellation (in digital modulation) into Capable mapping.Then, encoded and modulation symbol is split into parallel stream.Each stream be subsequently mapped into OFDM subcarriers, It is multiplexed in the time and/or frequency domain with reference signal (for example, pilot tone) and then uses inverse fast Fourier transform (IFFT) It is grouped together to generate the physical channel for carrying time-domain OFDM symbols stream.OFDM streams are by spatial pre-coding to generate multiple skies Between flow.Channel estimation can be used to determine coding and modulation scheme and be used for spatial manipulation.The channel estimation can be from by UE Reference signal and/or the channel conditions feedback of transmission are derived.Each spatial flow is then provided via separated transmitter To different antennas.Each transmitter modulates RF carrier wave for transmission with respective spatial flow.

At UE, each receiver receives signal by its respective antenna.Each receiver recovers modulation Information on to radio frequency (RF) carrier wave simultaneously provides this information to L1 layers of various signal processing functions.The information is held at L1 layers Row spatial manipulation is to recover any spatial flow using UE as destination.If there is multiple spatial flows are using UE as destination, then They can be combined into single OFDM symbol stream.Then using Fast Fourier Transform (FFT) (FFT) by the OFDM symbol stream from time domain It is transformed into frequency domain.The frequency-region signal includes individual OFDM symbol stream to each subcarrier of the ofdm signal.By determining most It is possible that the symbol and reference signal on each subcarrier are restored and demodulated to the signal constellation point transferred by eNB.These Soft-decision can be based on channel estimation.These soft-decisions be subsequently decoded and deinterleaved with recover it is original by eNB physics believe The data and control signal transmitted on road.These data and control signal are subsequently provided to higher processing.

The related term such as some and downlink reference signal and channel state information is described below.

Downlink reference signal

Downlink reference signal is that pre-defining for specific resource element (RE) is occupied in down time-frequency resource block (RB) Signal.In LTE downlinks, including following several different types of reference signals：

Cell special reference (CRS)：It is often referred to shared reference signal, all UE can be used in cell.

Demodulated reference signal (DMRS)：For specialized user, it is embedded in data.

Channel state information reference signals (CSI-RS):For estimating channel state information, to the resource of assistant base station Scheduling, precoding work.

Channel state information (CSI)

Channel state information is used to refer to the channel status of the channel between base station and UE.Channel state information may include Order designator (RI), precoding matrix indicators (PMI) and channel quality indicator (CQI).

RI is the information about channel sequence, and channel order instruction can carry different information in identical running time-frequency resource The maximum number of layer.

PMI is used to indicate the specific precoding in the code book including multiple pre-coding matrixes shared between base station and UE The index of matrix.

CQI indicates channel quality, can be used for assisting in corresponding modulation scheme and code rate.

In addition, CRI (CSI-RS resource indicator) is used to indicate the CSI-RS resource of preference, UE measures every CSI-RS moneys Source and in the form of CRI feedback recommendation spatial beams.UE can indicate that the UE qualities of reception are best by feeding back CRI to base station CSI-RS wave beams.

CSI processes (CSI-Process)

Can be that UE configures multiple CSI processes, to which UE is for the measurement and report of each CSI processes progress CSI.

Next full dimension MIMO (FD-MIMO) technology is simply introduced.

FD-MIMO technologies can by eNB using with for example be up to 64 antenna ports two-dimensional antenna array come Significantly improve power system capacity.May include using the benefit of mutiple antennas port interfering between small cellular cell at eNB and High beam forming gain.Allow carrying out the wave beam tax different because of UE in both horizontally and vertically the two using two-dimensional antenna array Shape.

In FD-MIMO systems, compared with 8 traditional antenna MIMO systems, the number of the transmitting antenna at eNB can be increased Add such as 8 to 10 times.These additional transmitting antennas can bring the beam forming gain of bigger and be introduced to adjacent cellular cell less Interference.

In traditional MIMO technology with one-dimensional aerial array, because of UE, different wave beam forming can go up quilt only in horizontal direction It executes.Multiple UE can be applied to by sharing vertical angle of declination.

In FD-MIMO technologies with two-dimensional antenna array, because of UE, different wave beam forming can in the horizontal direction and vertically It is performed in the two of direction.

In conventional linear precoding, eNB needs the mimo channel status information (CSI) about all channel.For example, traditional Wave beam forming/method for precoding dependent on entire transmitting dimension CSI availability (for example, it is desired to emit day from each eNB Instantaneous/statistical knowledge of the line to the channel of one or more UE reception antennas).

Such CSI is fed back by UE PMI/RI or is obtained by using channel reciprocity.In TDD (time division duplex) system In system, CSI is mainly obtained at eNB by using two-way channel reciprocity.In FDD (frequency division duplex) system, CSI is usual It is measured at UE and quantifies and then feed back to eNB via dedicated uplink channel.In general, CSI is used to quantify Code book size with the transmitting antenna at eNB number increase and increase.

The PMI/RI reports of UE can be estimated based on the pilot aided formula of DL all channels.Pilot tone (or common reference signal) is opened Pin and DL channel estimations complexity can be proportional to the number of eNB antennas.Therefore, the complexity of PMI/RI selections can be with eNB days The number of line increases and increases.And if based on the mechanism of known cooperative scheduling/collaboration wave beam forming, UE not only needs to service The related PMI report of cell is to eNB, it is also necessary to know the code book for the adjacent cell that may be interfered in advance and report interfered cell PMI.

The inter-cell interference in wireless communication system is simply introduced with reference to Fig. 1.As shown in Figure 1, wireless communication system 1000 include base station 1002,1004 and terminal device 1010,1012,1014,1016,1018.Terminal device 1010,1012 and 1014 are located in cell 1006, are controlled by base station 1002, terminal device 1016 and 1018 is located in cell 1008, by base station 1004 Control, cell 1006 are adjacent with cell 1008.

In embodiment of the disclosure, small to interference source by the UE of serving cell in order to carry out the interference coordination of minizone The reference signal sent by spatial beams in area measures, to determine the spatial beams of interference cell-of-origin to serving cell The interference that UE is generated.Step S2000~S2004 shown in Fig. 2 shows the ginseng that interference cell-of-origin is measured by the UE of serving cell A kind of example implementations for examining signal, are specifically described below.

As shown in Fig. 2, in step S2000, interference source base station notifies the reference signal of interference cell-of-origin to serving BS Configuration information.

According to one embodiment of the disclosure, interference source base station can be by the communication link between base station to serving BS The configuration information for the reference signal of notice interference cell-of-origin sent by spatial beams.Communication link between base station for example may be used To be primarily used for the X2 interface of the switching and the relevant information of interference of carrying minizone.In one example, interference source base station It can indicate that (load indication) message notifies the configuration information to serving BS by the load on X2 interface.Load Instruction process is used in control frequency between the base station of the neighboring community (intra-frequency) and between controlling frequency (inter-frequency) load and interference synergic information are transmitted between the base station of neighboring community.

According to one embodiment of the disclosure, in the case where receiving the request from serving BS, interference source base station The configuration information is notified to serving BS.

According to one embodiment of the disclosure, the reference signal that the reference signal of cell-of-origin can be special is interfered.According to Another embodiment of the disclosure interferes the reference signal of cell-of-origin that can utilize CSI-RS (such as the current LTE of wave beam forming Class B CSI, hereinafter also referred to BF-CSI-RS in standard) it realizes.

According to one embodiment of the disclosure, it may include instruction carrying to interfere the configuration information of the reference signal of cell-of-origin The information of position of the resource element (RE) of the reference signal in resource block (RB).In one embodiment, small in interference source In the case that the reference signal in area is BF-CSI-RS, interfere the configuration information of the reference signal of cell-of-origin may include instruction with Interfere the information of positions of the corresponding each BF-CSI-RS of each spatial beams of cell-of-origin in RB.In one embodiment, dry Disturb cell-of-origin reference signal be BF-CSI-RS in the case of, interfere the configuration information of the reference signal of cell-of-origin to may include By interfere cell-of-origin UE to interfere cell-of-origin BF-CSI-RS measure (such as measure BF-CSI-RS reception signal work( Rate (such as RSRP) or Signal to Interference plus Noise Ratio (SINR)) obtained from CRI, the CRI can indicate interference cell-of-origin in Power coverage Larger spatial beams, and then can indicate serving cell may be generated in interference cell-of-origin the spatial beams of larger interference. In addition, the configuration information of the reference signal of interference cell-of-origin may include the cell number for interfering cell-of-origin.

In step S2002, serving BS to the UE of serving cell notify interference cell-of-origin reference signal match confidence Breath.

According to one embodiment of the disclosure, in the case where it is BF-CSI-RS to interfere the reference signal of cell-of-origin, service Base station can configure multiple CSI-Process, wherein at least one CSI-Process by the UE that RRC signaling is serving cell For notifying the configuration information of BF-CSI-RS, the format of CSI measurement reports, CSI of interference cell-of-origin to survey to the UE of serving cell Amount report shared resource, trigger condition etc., and other CSI-Process can be used for the CSI report of serving cell.In this reality Apply in example, the UE of serving cell can according to the preconfigured CSI-Process of serving BS in specified subframe to service base Report of standing interferes the CRI of cell-of-origin, serving BS can know it is which CSI- according to the sub-frame number of its report received The CRI of Process, so as to determine the cell of the corresponding interference cell-of-origins the CRI according to the configuration of the CSI-Process Number, i.e. UE report the cell number of interference cell-of-origin in a manner of implicit.

According to one embodiment of the disclosure, serving BS can be by holding on Physical Downlink Shared Channel (PDSCH) CSI-IM (CSI interference measurements) resource in the RRC signaling of the RRC sublayers of load to provide interference cell-of-origin to the UE of serving cell BF-CSI-RS configuration information.For example, the configuration of CSI-IM resources is as shown in the following Table 1.

[table 1]

In table 1, the cell number of interference cell-of-origin is carried by " InterferenceCellId " variable, by The carrying of " InterferenceCRI " variable is by interfering the UE of cell-of-origin to interfering the BF-CSI-RS of cell-of-origin to be measured The CRI arrived.In addition, table 1 shows the case where BF-CSI-RS quantity of interference cell-of-origin is 8, correspondingly, above-mentioned CRI can be by Integer representation between 0~7 can also be indicated by the Bit String of 3 bits.It is interfering the BF-CSI-RS quantity of cell-of-origin When other values, similar design can be carried out.

It should be noted that table 1 show interference cell-of-origin configuration information include interfere cell-of-origin cell number and by The example of the case where CRI for interfering the UE of cell-of-origin that the BF-CSI-RS of interference cell-of-origin is measured, in interference source When the configuration information of the reference signal of cell includes other information, similar configuration can also be carried out by CSI-IM.

In step S2004, the UE of serving cell can measure interference cell-of-origin according to the configuration information obtained Reference signal, to determine interference of the spatial beams corresponding to the reference signal of interference cell-of-origin to the UE of serving cell.For example, The UE of serving cell can measure the received signal power of the reference signal of interference cell-of-origin according to the configuration information obtained (such as RSRP) or Signal to Interference plus Noise Ratio (SINR), and interference cell-of-origin and its interfering beam are determined according to measurement result.
